UNITED PHILIP HUFELAND, OF WVEST MOUNT VERNON, AND WILLIAM W. BATCH-ELDER, OF NEW YORK, N. Y.; SAID BATOHELDER ASSIGNOR TO SAID HUFELA'NDIMPROVEMENT IN LIGHTING ATTACHMENTSFOR GAS-BURNERS.

Specification forming part of Letters Patent No. 180,588, dated August1, 1876; application filed 1 July 7, 1876.

To all whom it may concern:

I Be it known that we, PHILIP HUFELAND, of West Mount Vernon, in thecounty of Westchester and State of New York, and WVILLIAM W. BATOHELDER,of New York, in the 'county of New York and State of New York, haveinvented certain new and useful- Improvements in Lighting Attachment forGas-Burners, of

.its flame will readily ignite the gas escaping from said burner, saidhydrogen-jet co-operating with a platinum sponge secured to a supportwhich may be conveniently attached to the burner, in such manner thatwhen the jet of hydrogen is projected upon the platinum sponge it willbe inflamed, and thus serve to ignite the jet of ordinary gas escapingfrom the burner. v

In the drawing, Figure 1 represents a view of an ordinary gas-bracket,showing our improved automatic lighting attachment secured in position.Fig. 2 represents a detached view of the burner, showing thehydrogen-jet and platinum sponge in position. Fig. 3 represents avertical section of the hydrogen-generator, showing the means forattaching the same to the bracket, and Fig. 4 represents a view of thecut-01f employed in connection with the flexible tube leading from thegenerator to the hydrogen-jet.

In the drawings, the letter A represents an ordinary gas bracket orchandelier. The letter B represents a vessel of glass or other materialcapable of resisting the action of acids, of any desired shape and size,but preferably of an ornamental configuration. The letter 0 representsan inverted bell or tube constructed of glass or other material capableof V resisting the action of acids, and adapted to set within the vesselB, and to be secured within the mouth of the same in any convenientmanner. In the present instance said bell or tube is provided with arubber, provided with a packing at its upper end, which holds it in themouth of said vessel when in place. The upper end of said tube isprovided with a loop or hook, B, by which the whole may be convenientlyattached to, and detached from, the gas bracket or chandelier. Said bellis provided with a hook depending from its top on its interior. which isadapted to hold or support a hooked rod, the lower end of which carriesa cylinder of zinc, E, for the generation of the hydrogen gas inconjunction with the acidulated water with which the vessel B ischarged. From the top of the bell projects a tube, F, provided with ashort tube, G, to which one end of a flexible tube, H, is secured, theother end of said tube being attached to one end of a hydrogen-jet, J,attached to the gasfixture in any convenient manner, its upper endterminating below the orifice of the burner K and in close proximitythereto. In the present instance the tube F is provided with a flange,f, on its lower end, and a movable disk, j", the exterior of said tubebeing screw-threaded and provided with a thumbscrew, F, by means ofwhich a packing, P, may be tightened in the mouth of the reservoir B, soas to hold the same upon the tube. The reservoir is provided with anaperture, 0, for the admission of air. L represents a platinum spongesupported above the hydrogenjet in a ring secured to anattachmentfastcued to the gas fixture or burner in any convenientmanner. In the present instance both the hydrogen-jet and the supportingattachment for the platinumsponge are secured to a small bracket, M,which encircles the screwthreaded end of the gas-bracket, and isconfined thereon by the burner; but it is evident that these devices maybe attached by other means. The flexible tube or gas-jet is providedwith suitable means for cutting off the flow of hydrogen. In the presentinstance this means consists of. a spring cut-oft, N, adapted to pinchor clamp the flexible tube and stop the flow, and to free the said tubewhen desired by pressing the sides together, the tube opening out by itsown elasticity when freed from the pressure of said cut-off.

' The operation of our invention will be understoodt'romtheforegoingdescription. When it .is desired to light the gas, the cockin the bracket is properly turned, and the eut-ofi' or cook of thehydrogen-tube manipulated so as to allow a jet of hydrogen to beprojected against the platinum sponge, when the. hydrogen becomesimmediately ignited, communicating its flame to the escaping gas. Uponclosing the cutoff the flow of hydrogen is stopped, the gas accumulatingin the bell, forcing the acidulated water away from the zinc, andstopping the generation of gas until it is again drawn off from the bellfor the purpose of again lighting the jet.

It is evident that the reservoir may be applied to a chandeliercontaining many burners by providing each burner with a platinum spongeand hydrogen-jet as described, with suitable flexible tubes leading fromsaid generator to the hydrogen-jets, so that as many burners as desiredmay be lighted by means of a single hydrogen-generator.

What we claim, and desire to secure by Letters Patent, is

A detachable hydrogen gas generator, adapted to' be secured to a gasbracket or chandelier, in combination with a hydrogengas jet andplatinum sponge, secured to the burner or other portion of thegasfixture, the generator being-connected with the hydrogenjet by meansof a flexible tube, substantially as set forth.

In testimony that We claim the foregoing we have hereunto set our handsin the presence of the subscribing witnesses.
